- # Test Composed Model — verifies the [composed_model] mechanism (symlink
- # composition + bind-mount + model rewrite) without launching heavy vLLM.
- #
- # Uses alpine (like test-sleep/test-mods) with a heartbeat entrypoint that
- # first inspects the composed dir, then loops. Requires both model repos
- # cached on every node — the composed dir's symlinks point into the HF cache
- # (container-side /root/.cache/huggingface), so they only resolve inside the
- # container where the HF cache is mounted.
- #
- # What this verifies:
- # 1. The composed dir is built on the node (/tmp/sm121_test-composed_<rank>/)
- # 2. MXFP4 base files are symlinked (config.json, tokenizer, etc.)
- # 3. Lloyd NF4 experts overlay the MXFP4 experts (L*.safetensors)
- # 4. The generated nf4_layers.json file is present
- # 5. The bind-mount makes /root/model/ accessible inside the container
- # 6. model= is rewritten to /root/model (visible in the docker run command)
- #
- # Usage:
- # cargo run -- -d serve --recipe test-composed # dry-run: inspect cmd
- # cargo run serve --recipe test-composed # real: starts alpine
- # cargo run logs --recipe test-composed # see the composed dir listing
